constant-voltage charger is a circuit that recharges a battery by sourcing only enough current to force the battery voltage to a fixed value. constant-current charger is a circuit that charges a battery by sourcing a fixed current into the battery, regardless of battery voltage. FIGURE 1. BATTERY CHARGE/DISCHARGE CURVE
The following battery characteristics must be taken into consideration when selecting a battery: 1) Type See primary and secondary batteries page. 2) Voltage The theoretical standard cell voltage can be determined from the electrochemical series using Eo values: Eo (cathodic) – Eo (anodic) = Eo (cell) This is the standard theoretical voltage.
Typical values of voltage range from 1.2 V for a Ni/Cd battery to 3.7 V for a Li/ion battery. The following graph shows the difference between the theoretical and actual voltages for various battery systems: The discharge curve is a plot of voltage against percentage of capacity discharged.
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
The relationship between the charging voltage and the battery charging current limit can be expressed by the formula: Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm.
The voltage of a battery is a fundamental characteristic of a battery, which is determined by the chemical reactions in the battery, the concentrations of the battery components, and the polarization of the battery. The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage.
